AEROPLANE.

Application led September 3. 1927. Serial No. 217,346.V

Fig. 1 is a top plan view of myimproved aeroplane.

Fig. 2 1s a side elevational view thereof.

Fig. 3 is a front elevational view thereof.v Fig. 4- is an enlarged fragmentary sec-l tional View taken on the line 4*-4 of Fig. 2.

Fig. 5 is a fragmentary sectional view illustratingl particularly the means of pivoting the wings of my improved device.

Fig. 6 is a similar fragmentary seetimal view thereof.

Fig. 7 is an enlarged fragmentary View illustrating a modification of my improved aeroplane.

Fig. 8 is a transverse sectional View taken on the line 8-8 of Fig. 7.

As here embodied my improved aeroplane comprises a body l0 of hollow construction. preferably of eylindrical shape and pointed at either extremity. The body l0A is of frame construction, covered with any desired suitable material. so as to provide suitable accommodations for the operators and passengers.

A motor 11, such as usually employed to propel aeroplanes is mounted in the fore part or forward extremity ot'- the body 10, and has-attached thereto, the usual propeller 12. as a means of propelling my improved aeroplane.

A pair vof wings. comprising the usual Aupper and lower mend-.ers 13 and 14, supported by the struts 15. are extended hori- Zontally from the sides ol' the. body 10. The.

said wings are secured tothe rod 16. pivot.-

' ally mounted, as at 17, in the sides of the bodyY 10.v A pair of sectors 18, are secured to the. -rod 16, and mesh with the'worms 19, secured to the shafts 20, rotatively mounted as at 21, and 22 in extended elements of the. body 10. The bevel gears 23 are attached to the shafts 20 and mesh with the bevel gears 24 attached to the shafts 25, rotatively mounted in thefliody l0. The crank members 2G are attaelied 4to theshatts 25. and

are provided Xv'ith handle elements 27.

The above described construction is such as will permit' the said Wings to be. pivoted in any desired 'angular position so as to permit my improved aeroplane to ascend and deseend as may be desired.

A stud 28 is adapted to engage in an aperture formed in the wings, and in anare opening forn'led in the body 10, as a means ot holding the said wings in any desired au; 'ular'position` bv tightening the nut 29, tlueadedly7 attached to the stud 28. so as to force the lock nut 30 in position thereon.

A second motor 31 islnounted inthe body 10. and is' provided with a bevel gear 32, secured to the' crank shaft of the said motor. The bevel gear 32. meshes with the bevel gear 83. secured tothe shaft 34. rotatively mounted in the body l0. The propeller 34 i is secured to the 'extended extremity. of the.

shaft 34, and is positioned horizontally. The above described construction is such as Will permit the propeller 35. eoaeting with the propeller-s hereinafter described. to elevate or raise the said aeroplane.

The bevel gear 36. meshes with the above mentioned bevel gear 32. and is attached to the shaft 37. rotatively mounted in the body 10. and in the bracket 38. seeured to and extended from the upper portion of the body. Sprocket wheels 39 are attached to the shafts 40 and 4:1, rotatively mounted in the upper portion of the. body l0. and the bracket 38. The chain 42 is extended over the sprocket wheels 39, and engages a similar sprocket wheel 43- attaehed to the shaft. 37. The Propellers 44 are provided with threaded central apertures, adapted to engage the threaded upper portions of the said shafts 37. 40, and 41. which are provided with enlarged extremities, as a means of holding 'the propellers 43 in place on the said shafts.

assumed the latter mentioned position` vrill with extended elements 79 engaging in elonat that time assist the propeller 34 in lifti'n the said aeroplane. I havc also provide locking members 46 which may be engaged over the threaded portions of the said shafts, so as to hold the. propcllers 44, in a fixed position on lhc said shafts.

l have also provided the usual rudder- 47, hinged as at 48, to the. tail member 49, and provided with a. tiller 50. Flexible members 51 and 52 are connected to the extremities of the tillcr 50, and to the. bell cranks 53 pivotally attached as at 54, to the body 10,

-of the aeroplane. The bell' cranks 53 are provided with handle elements p 55, as a means of pivoting the rudder 47, so as to steer my improved aeroplane. to the right or to the left.

l have also provided thc usual landing Wheels 56, secured to the shafts 57, rotatively mounted in the brackets 58, Aextended from and secured to the body 10, such as are ordinarily provided to assistin landing.

It wlll be understood that the body 10, has hinged thereto, a door 59, permitting access to the interior of the body 10, which is provided with a compartment 60, equipped with a suitable seat 61, and control board 62, to accommodate the usual control mechanism for manipulatinethe motors of my improved aeroplane. It should be further understood that I do not necessarily limit my improved aeroplane to the particular construction, as above set forth a's regards the body'accoutremcnts, but to all types and classes of bodies, such as used for passenger or freight service, or in modern warfare.

In Figs. 7 and 8 of the accompanyingr draWing,'I have shown the sprocket wheels 39, rotatively mounted on the shafts 40 and 41. The disc members 65 are slidably mountcdon the shaft-540 and 41, and arc secured thereto, by keys 66. The pins 67 are secured to and extended from the disc members 65, and are adapted to engage inv apertures 68, formed in the sprocket wheels 39. The expansion springs 69 normally hold the pins 67 in disengagement with the said apertures formed in the sprocket wheels. The' levers 70 are pivotally attached inter- I mediate to thc lug elements 71 of the above mentioned bracket 38 and are provided with forked extremities 72, engaging the disc members 65. The rods 73 are plvotally attached, as at 74 and 75, to the lever 70, and to the lever 76, ivotally attached intermediate to the bra et 77, secured to an suitable, convenient part of my improve aeroplane. The threaded blocks 78 are'provided gated openings formed in one extremity of the levers 76. The threaded blocks 78A are adapted to receive the screws 80, rotatively mounted in the brackets 8l and 82, secured to any suitable convenient part of my improved aeroplane.. The crank 83 is secured to the screw S0, and is provided with a handle 84.

The above described conslriulion is such as will permit the shafts 40 and 4l to-be rotated bythe sprocket wheels 39, when the. pins 67 are engaged in the apertures 68, by means of rotating the cranks 83. This constructionv is provided as a means of permitting the propellers 44 lnounted on the said shafts 40 and 41 to be operatively connected, as may be desired, so as to permit my improved aeroplano to be lifted gradually, increased lifting power thereby being secured.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. In a device of the class described, a propeller operatively connected With a prime mover and arranged for lifting the device.,

shafts connected for rotation together with' the said propeller, and having threaded portions, and propellers threadedly engaged on the said threaded portions and arranged for lifting the device. l

2. In a device of the class described, a propeller operatively connected wi th a prime mover and arranged for lifting the device, shafts connected for rotation together with the said propeller, and having threaded portions and enlarged extremities, and propellers threadedly engaged on the. said threaded portions and held against displacement oiln of the shafts by the said enlarged extremities and arranged for lifting the device.

3. In a device of the class described, a y
